Her style has been compared to that of Carmen McRae (the two singers were friends). Dana Countryman quotes from Linda Dahl's 1984 book on women in jazz, Stormy Weather: "Irene Kral had a lovely, resonant voice with a discreet vibrato, flawless diction and intonation, and a slight, attractive nasality and shaping of phrases that resembled Carmen McRae's. But where McRae's readings tend to the astringent, Kral's melt like butter. She was a master of quiet understatement and good taste."[1]
